Be it known that I, CHARLns E. Knees, a citizen of the United States,and a resident of Chicago, Cook County, and State of Illinois, haveinvented certain new and useful Improvements in Mopv Heads, of which thefollowing is declared to be a full, clear, and exact description.

This invention relates to mopheads or mop swabs (for use with Water forcleansing purposes as distinguished from oil mops, dry mops andchemically treated mops for dusting, or dish mops) and its principalobject is to prolong the life and increase or enhance the efficiency ofarticles of this nature. The ordinary mophead is usually constructed ofa plurality of separate lengths of so called mop yarn, made of strandsof fibrous material twisted together, these separate lengths of socalled mop yarn being grouped and, in accordance with one`form of mop,fastened midway between their ends with a strip of tape or the like;and, in accordance with another form of mop, is constructed byfastening, in various manners, to the end of a stick or handle, 'agrouped plurality of separate lengths of so called mop yarn made ofstrands of fibrous material twisted together. The great. objection tosuch mopheads is the inherent tendency of the strands, individually andcollectively, of the twisted so called mop yarn, to untwist immediatelyand rapidly after put into use. The result is that when the individualstrands' untwist, the mop yarn, which is composed of theseY individualstrands, disintegrates rapidly and the fibres and batches of fibre fallaway from the mophead or mop swab proper.v After a. mophead, made ofstrands, twisted together to form so called mop yarn, has been in use ashort time, numerous particles or batches of fibers of the strands,individually and collectively, untwist, loosen and separate and aredeposited on the floor. On account of the quick and constant fallingaway of these fibers the mophead itself soon wears away to such anextent that it is'inelficient for mop ing.-

I have effectively overcome these o jectionable features in mopheads byproducing' a mophead or mop swab in-which the separate lengths of thefibrous material composing the mophead or mop swab, are formed ofbraided, woven, or otherwise interlaced strands of absorbent material,vwhereby the .v 11566-544' PATENT l l' CHARLES E.

tendency of the strands, individually andl i collectively, to untwist,loosen and separate from each other is reduced to a; minimum. lIn fact,when saturated with water, .the vlibers of the strands and the strandsthemselves, individually and collectively, of each separate length ofthe material, have a tendency to become impacted and are subject only tosuch disintegration andloss of fibers as is occasioned by the ordinaryabrasion, friction andA wear and tear on the mop.A In order to obtainthe most effective results with a mophead embodying the presentinvention, it is necessary that the strands-of the separate lengths ofmaterial be so braided, woven, or otherwise interlaced, or'

suitably arranged as to looseness orl tightness, that the separatelengths may readily, quickly and -copiously absorb water.

` With the above named objects and advan-.

tages in view this invention consists of a mophead formed of a groupedplurality of braided, woven, or otherwlse suitably interlaced separatelengths of fibrous or other i absorbent material. .It further consistsof the other several novel features hereinafterv ment of one of theseparate lengths of ,ab-

sorbent material of which the mophead is made; Fig.v 3 is a sideelevation of a fragment of a slightly modified form df the separatelength of absorbent material from which the mophead is constructed, andFig. 4 is a perspective view of a fragment ofv another modified form ofseparate length absorbent material from which the mophead isconstructed;

Referring to said drawing, a mo head illustrating a simple embodiment othis invention is seen at A, and in accordance with one style or form ofmop, is made up of a plurality of separate lengths a, of absorbentmaterial formed of braided or otherwise suitably interlaced fibrousstrands, the separate lengths being grouped to form a swab-likestructure secured together as for instance with a bindino' strip b, oftape or the like.' Usually the b1nding strip is sewed to and around thegrouped separate lengths loo' terial, a,`are formed. of fibrous strandsa1,

' mophead is which in accordance with one of the forms of the inventionare braided or otherwise interlaced as seen in Fig. 2. Any desirablenumber of strands of fibrous material may be used in each separatelength of material, but it is necessary to braid, Weave or otherwiseinterlace the separate lengths of material in a relatively loose mannerin, order to rovide a structure that will be readily absorbent, pliableand easily handled when 1n use.

'In the form of the separate length fibrous material illustrated in Fig.3, the strands of fibrous or other absorbent material a2 may be twistedtogether in accordance With the common practice to form ordinary mopyarn, and to prevent the twisted together strands of the separatelengths from rapidly untwisting, loosening and separating, I surroundthem with an open work or net like casing or cover formed of fibrousmaterial a3, which. may be in the form ot a woven, braided, interlacedor otherwise formed tube of reticulated fibrous material. Thereticulated easing may be made of relatively strong material such asstring, twine or the like and the center section or core, may be made ofstrands of fibrous or other absorbent material. In this form of theinvention also the strands of the center section or core, individuallyand collectively, are effectively prevented from rapidly untwisting,loosening and separating, as the fibers thereof are held togethereffectively by the braided, woven, interlaced or otherwise arranged,open work or net like easing or cover, with the result that the life ofthe greatly prolonged and the inherent objectionable feature of rapiddisintegration of ordinary mops by untwisting, loosening and separatingof the fibers 1s eliminated.

It will be understood that the separate lengths of absorbent materialmay be solid, or they may be hollow or tubular, Aas lllusl rapid whichit is composed as illustrated in Fig. 2,

or they may be otherwise suitably secured.

to prevent rapid disintegration thereof..

More or less variation of the exact details of construction of theseparate lengths of mop material is possible without deviating from theintent or object of this invention; I desire therefore, not to limitmyself to the exact iorm of the construction shown and described, butintend in the following claims to point out all of the inventiondisclosed herein.

I claim new, and desire to ser-.ure by Letters Patent:

l. A mophead composed of' a grouped plurality of separate lengths ofabsorbent material, each separate length of material having interlacedstrands at its exterior portion, arranged to prevent rapiddisintegration of said separate length of absorbent material.

2. A mophead composed of a grouped plurality ot' separate lengths offibrous material, each separate length of fibrous niaterial consistingof interlaced strands, arranged to prevent rapid disintegration' of saidseparate length ot mop material.

3. A mophead composed of a grouped plurality of separate lengths ofabsorbent material, each separate length of absorbent material havinginterlaced strands at its exterior portion and the strands at theextreme ends of each separate length of absorben-t material beingfurther interlaced to prevent disintegration thereof.
